About This Assembly

RG400 Cable

RG-400 is a double-shielded, silver-plated PTFE coaxial cable built to MIL-C-17 specifications with a 0.195" outer diameter. Its construction mirrors RG-142 but with two braid shields for even greater shielding effectiveness. The standard cable for military and avionics applications requiring certified materials and traceable performance.

FME Connector

FME (For Mobile Equipment) is a miniature threaded RF connector designed for mobile and vehicle-mounted antenna applications, particularly at GSM, CDMA, and FM frequencies. Its small size and robust threaded coupling make it common on vehicle-mount antenna mounts, cellular signal boosters, and mobile broadband modems.

MCX Connector

MCX (Micro Coaxial) is a snap-on RF connector approximately 30% smaller than SMB, designed for compact equipment requiring frequent connections in a small footprint. Rated to 6 GHz, MCX is commonly used in GPS receivers, automotive telematics modules, handheld communication devices, and compact measurement instruments.

Common Applications

This FME and MCX cable assembly is well suited for military-spec RF interconnects and avionics signal routing. The combination of reliable FME and MCX connectors and custom-cut cable length makes it a practical choice for both field installations and bench setups. Every assembly is hand-terminated, continuity tested, and ships free within the USA.
